What

I think we can improve TypeTransformer to convert simple type (string, number, integer, boolean, null) values
to array of this values if schema requires array of simple type

For example:

schema = {
    "type": "object",
    "properties": {
        "value": {"type": "array"}
    }
}

{"value": 1} -> {"value": [1]}
{"value": "string"} -> {"value": ["string"]}
{"value": "string"} -> {"value": ["string"]}
{"value": True} -> {"value": [True]}
{"value": 1.5} -> {"value": [1.5]}

1. If value is not simple type ("array", "object") we DON'T DO such conversion:

{"value": {"key": "value"}} -> {"value": {"key": "value"}}  #  nothing changed

2. if array-items is complex type DO nothing

schema = {
    "type": "object",
    "properties": {
        "value": {
            "type": "array",
            "items": {"type": ["object"]}   # <- complex type
        }
    }
}

{"value": 10} -> {"value": 10}  # nothing changed 

3. additional conversions inside array still works as before

schema = {
    "type": "object",
    "properties": {
        "value": {
            "type": "array",
            "items": {"type": ["string"]}
        }
    }
}

{"value": 10} -> {"value": ["10"]}

Good addition! Just for simplicity, could you release only 1 version of the CDK containing all 2-3 changes you recently made in the separate PRs?

@sherifnada ok I will publish together with #16695
